Abstract: A thin film path of medium resistivity provided by a strip of tantalum by which a design parameter of an electronic component is determined is modified by making contact with the path by an electrode having an electrolyte at its tip in passing an anodizing current into the path through the electrode that is much smaller in value than the normal current flowing through the path under design conditions of operation. In consequence, the current injected to produce chemical change in the resistance has a negligible effect on the characteristics of operation of the component and the component can have operating conditions applied to it during the trimming process can be carried while the component is under operating conditions and the parameter to be adjusted is being measured, so that the measurements of the parameter can control the current injected through the electrode so as to shut it off when the desired value of the measured parameter is reached.

Abstract: A plurality of sensors are located on one of the bodies, staggered by fixed distances from each other along the direction of relative movement. The sensors are responsive to a characteristic of the other body, for example to surface characteristics of a roadway. A sensed signal, picked up by a first, or leading sensor is time delayed for a predetermined time interval, and compared with signals received from all the other sensors. Upon optimum correlation, and with known time delay and distance between sensors, the relative speed can then be indicated by determining which one of the sensors picked up the signals which matched the time delay signal. The amplitudes of the signals can be dynamically equalized and the time delay itself changed to permit output over wide ranges, or with respect to different scaling units.

Abstract: To simplify electronic fuel injection or ignition signal generation, a transducer is provided which is formed as a segmental element providing a first or starting pulse at a certain angular position of the crankshaft of the engine and a second or termination pulse when the crankshaft of the engine has moved through a predetermined angle. A frequency controllable oscillator, typically a voltage controlled oscillator (VCO) forming part of a phase locked loop (PLL) provides counting pulses to a first counter 12, the first counter counting from the start to a termination number and then providing the trigger signal.

Abstract: A first thyristor, under control of a speed setting provided in an RC circuit varies the phase duration of current supply to the motor during positive halfwaves of the a c supply, and a second thyristor controlled in accordance with the motor current provided through the first thyristor determines the phase angle during which current flows through the motor in the negative halfwave of the voltage supply, so as to maintain the speed at the set value under varying conditions of load. During positive halfwaves, a capacitor is charged to a voltage corresponding to the amount of current flow through the motor and during the following negative halfwave, the charge is increased at a rate set by an RC circuit, resulting in turning on the second thyristor early under heavy load conditions, and late under light load conditions, and indeed not at all under idling conditions.

Abstract: A snowmobile comprises a vehicle body, a suspension mechanism connected at a lower portion of the vehicle body and a torsion mechanism for preventing the outward inclination of the vehicle body when the snowmobile is turned. The tension mechanism is provided with a U-shaped tension member which consists of a pair of arms and a base. The arms extend lengthwise of the vehicle body and have their free ends connected to the rear portion of the suspension mechanism. The base has its both ends secured to the other ends of the arms and is made of material of high torsional rigidity and rotatably supported by the vehicle body. When the snowmobile is turned quickly, the torsion mechanism acts to substantially equalize the downward flexture of both lateral side portions of the suspension mechanism, thereby to prevent the vehicle body from being excessively inclined outward of its turning under a centrifugal force exerted thereon.

Abstract: The provision of a supplementary layer of nickel by an electroless process in order to provide solder wetting capability for a tempered aluminum-nickel metallization is made unnecessary by causing the layer of nickel deposited on an underlying aluminum metallization layer to have a thickness between 0.6 and 1.0 .mu.m and by conducting the subsequent tempering operation between 400 and 480.degree. C, preferably 475.degree. C, for a period of between 10 and 20 minutes, preferably 15 minutes. In order to provide high transverse conductivity, the aluminum layer should have a thickness between 3 and 10 .mu.m. The process is useful in the manufacture of semiconductor devices as well as for making electrical devices based on an insulating substrate.

Abstract: A core with at least three elongated legs, at least one leg being centrally located among all the elongated legs, is joined at at least one end by a yoke portion connecting all the legs. The central leg or legs is wound with a magnet winding close to the yoke portion of the core, with which the core is excited with an alternating field. A short-circuiting ring structure, which may be in the form of an apertured plate, encircles at least the central leg or legs of the core and is movable in the direction of elongation of the core in accordance with the movement of a body the displacement of which is to be measured. The legs of the core may be bent in order to measure rotational or angular displacement. Movement of the short-circuiting ring along the length of the core varies the inductance of the coil in a predetermined manner, which may be a linear relation to displacement. A yoke and a winding may be provided at the other end in order to increase the sensitivity by a differential method of measurement.

A specific row of a heading column in the matrix in the processing memory means is address designated to permit the address position data in this row to be sequentially shifted in a row direction. Specific codes, each written in an address position following a final character data, in the word data are counted by a counter while an address shift is effected in a column direction from an address position in the specific row.

Abstract: In a pack for eggs or other fragile articles constructed of corrugated strips glued to and braced by external flat strips, in which the corrugated strips are joined together at their inner apices and folded at these junctions after the manner of U.S. Pat. Nos. 3,955,744 and 3,983,680, the closure of the pack is made along one of the narrower sides instead of along one of the wider sides, and at least one of the abutting narrow flat strips is provided with tongues of a length greater than the width of the strip that are stamped out of the material of one of the wider flat strips. These tongues are bent over so as to overlap the adjoining flat strip, where they can be glued to the flat strip to hold the pack together. The fastening is thus provided out of the material of the pack without waste, and no fasteners or adhesive strips need be applied from an external source in the packing operation.

Abstract: To avoid temperature shock and mechanical damage to oxygen sensors with ion conductive solid electrolytes exposed to the exhaust gases of internal combustion engines, a catalyst, for example in the form of aluminum oxide pellets having a catalyzing surface layer, is located to surround the oxygen sensor, or just in advance of the oxygen sensor in a bypass pipe, branching off from the exhaust gas pipe of the engine to take samples of the exhaust gases so that the sensor and catalyst form an assembly, or sensing combination. The catalyzing layer may be platinum, or a platinum metal, or an alloy of platinum with aluminum, cobalt, nickel, or chromium, or may be mineral wool, or wool of glass, or asbestos fibers having their surface coated with any of the foregoing catalysts.

Abstract: Pulse sequences from a radar receiver respectively made up of successive start pulses and of successive echo pulses from one or more targets are expanded in time by multiplication with an auxiliary pulse sequence differing slightly in repetition rate from the start pulse sequence. This enables circuits to be used with a lower degree of time resolution that would otherwise be needed, at the cost of proportionally reducing the number of individual measurements of the target distance, a cost which is of no substantial consequence in an anti-collision radar where the closing rates are small compared to the pulse repetition rate. A time-expanded sequence of reference pulses is similarly produced from the oscillator controlling the repetition of the radar pulses and the auxiliary oscillator in order to make the measurements independent of signal propagation times within these circuits.

Abstract: An electronic timepiece uses a dynamic type shift register, as a time count circuit, which has a plurality of memory sections corresponding to an equal number of time count units and a cycle number memory section arranged such that it is preceded by said plurality of memory sections. An adder and shift memory unit are serially connected to the shift register to provide a shift circulation circuit and the shift circulation is effected by an oscillation signal from a reference oscillator. The adder adds [1] to the contents of the cycle number memory section for each data shift cycle of the shift register. Each time the count value of the cycle number memory section reaches a predetermined cycle number, the count value of a smallest time unit is counted one step. In this way, a carry is propagated to the subsequent large time unit memory sections according to the data shift circulation cycle of the shift register.

Abstract: A saw-tooth wave generator including thyristors is provided in the vertical deflection circuit, the thyristors controlling charging and re-charging of a charge capacitor. A portion of the energy contained in the line retrace and delivered from the horizontal output stage is used in order to provide current for the vertical deflection coil. In order to prevent spurious or erroneous operation of the thyristors, an oppositely poled bias voltage is applied to the gates of the thyristors during the pauses or intervals of triggering of the thyristors, the bias voltage being derived externally or directly from the thyristor control circuit, for example by utilizing the inductive reverse-polarity kick of an inductance connecting the thyristor gate to its control circuit, by a charge-reverse re-charge circuit of a capacitor, or the like.
